One of the lorries tipped over onto its side during the collision blocking all three lanes.
While work to recover the vehicle is due to get under way shortly we’re unable to give a time estimate of how long this will take and the motorway will remain closed for some time.
I appreciate the closure will have caused problems for commuters this morning and I thank the public for their continued patience while we deal with this incident.
